    摘要: Embodiments contemplate methods, systems, and apparatuses for interference measurement in a wireless communication network, including wireless communication networks the employ MIMO in uplink and/or downlink communication. Embodiments contemplate identifying one or more interference measurement resource elements that may be received from one or more transmission points. Embodiments also contemplate performing interference measurement estimation based at least in part on the identified one or more interference measurement resource elements. Channel state information (CSI) perhaps in the form of reports may be generated based at least in part on the one or more interference measurement estimation. Embodiments also contemplate that the CSI report may be transmitted to one or more nodes. In some embodiments, the one or more interference measurement resource elements may be received as part of a set of resource elements.

    摘要: Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.

    摘要: A method and apparatus of performing selective internet protocol (IP) selective offload (SIPTO) or local IP access (LIPA) is disclosed. A wireless transmit receive unit (WTRU) receives a broadcast message from a Node-B. Then the WTRU receives a message from the Node-B that SIPTO service, or LIPA service is available for that WTRU. The WTRU then communicates using the SIPTO or LIPA service. A method an apparatus for receiving a paging message for SIPTO or LIPA services is also disclosed. The paging message includes an indicator that indicates that the message is for SIPTO or LIPA communications. The indicator may be a temporary mobile subscriber identity (TMSI) assigned by the network specifically for SITPO or LIPA communications. The indicator may also be a single bit designated to indicate that a paging message is a for SIPTO or LIPA traffic.
